Diamond cutting blade Diam BS70 laser 400 mm × 25.4/10 for professional use

Diamond cutting blade Diam BS70 laser 400 mm × 25.4/10 for professional use is a laser-welded segmented diamond blade engineered for high-performance cutting of stone, concrete and other hard building materials. With a 400 mm diameter and a dual-bore configuration (25.4/10 mm), the blade is intended for use on compatible high-power circular saws and bridge saws in construction and masonry environments. Laser welding secures the diamond segments to the steel core to provide stable cutting, extended segment life and consistent performance under heavy loads.

Advantages

The laser-welded diamond segments offer improved adhesion and resistance to heat and impact compared with brazed designs. The 400 mm diameter provides a balance between cutting depth and power requirements, while the segmented rim design facilitates fast material removal and effective cooling. The dual-bore configuration increases mounting compatibility with professional saws, and the steel core is built to withstand the torque and rotational speeds typical of construction saws.

Suitable for

• Cutting natural stone such as granite and marble
• Cutting reinforced and plain concrete
• Masonry block and paver trimming
• Precision cuts on building site panels and tiles

Key specifications

• Diameter: 400 mm
• Bore configuration: 25.4 mm / 10 mm (dual-bore)
• Segment type: laser-welded diamond segments
• Blade design: segmented rim for aggressive cutting and cooling
• Intended mounting: compatible with high-power professional circular and bridge saws
• Primary materials: stone, concrete and similar hard building materials

How to use

Mount the blade on a saw that supports a 400 mm diameter and the 25.4/10 mm bore configuration, ensuring the saw is rated for the blade’s intended use and rotational speed. Check that the blade rotates in the correct direction indicated on the blade and that all guards and safety devices are in place. Use steady feed pressure and maintain consistent cutting speed to avoid overheating; allow water cooling if the blade and saw are configured for wet cutting. Inspect the blade regularly for segment wear or damage and replace it when performance degrades or visible damage is present.

Usage recommendations

For optimal life and cutting quality, use the Diam BS70 laser blade on machines with sufficient power and torque, select wet cutting where possible to reduce heat build-up, and match cutting speed to material hardness. Ensure correct arbor fit using adapter rings if required, and follow all machine manufacturer safety guidelines and personal protective equipment requirements.
